Description

Technical Field

[0001] The utility model relates to the technical field of kiln waste heat utilization, and in particular to an AB mutual assistance waste heat utilization system for a shuttle kiln. Background Art

[0002] In traditional sanitary ceramic factories, shuttle kilns usually use air as a combustion-supporting gas when firing products. When firing products, the air is mixed with combustible gas and flames are continuously ejected into the kiln after ignition. The temperature of the air is consistent with the ambient temperature of the kiln, usually between 20-50°C. When firing sanitary ceramic products, the flame temperature usually needs to be above 1100°C. Using room temperature air as the combustion-supporting air will cause part of the gas heat to be used to heat the air, resulting in energy waste. Therefore, people in this field are in urgent need of finding a new technical solution to solve the above problems. Utility Model Content
